Dear List members,
We are currently working on an experiment about the semantical=20 processing of environmental noises. We are trying to do a similar task=20 as the lexical decision task with words and nonwords, but with=20 environmental noises and "non-noises". The problem is that we have a=20 hard time creating non-noises which are quite environmental noise-like,=20 but are not recognizable. We tried almost every distortion methods used=20 in the literature (reversing, spectrally-rotating, scrambling the parts)=20 but the sounds are always pretty much recognizable by most people. Does anyone have any idea on how to create such non-recognizable=20 non-noises based on existing environmental noises? Or is this idea just=20 not feasible, because people will always think that what they heard is=20 something real? Thanks, Ferenc Honbolyg=F3
